Boulder Creek is really, really low right now. I have never seen it this low. However, the fish are very hungry and looking up. Any depression in the stream bed, I mean no more than a foot or so, is likely to hold a fish or two. But you only get one chance and then the spot is done. If you find a deeper pool, put on a dropper and fish about a foot off the bottom. Above the falls in the steeper sections the water tends to pool more. Move often and make as few false casts as you can to get the most fish to respond. While there are larger fish in the system, you can expect to catch 8-12 inch browns with the occasional rainbow. Get them back in the water fast and pinch down barbs. You may only hook half the fish that come up to the top, but you will get a lot of chances and the action is fairly predictable.

yes, Boulder creek has been so low that I have been doing more carp and bass fishing. Or, hiking up in Indian Peaks to go after cutts and brooks.

Mid canyon was good the other evening with a dry dropper setup.
Hopefully we will get some fall rain to bump up the stream before it gets cold.
There are a few big browns, but they are very spooky.
Seems like less and less rainbows in Boulder creek.
